一、介绍

主要技术:

(1)s2sh之间的整合

(2)dwr和s2sh整合(验证姓名是否相同)

(3)强大的jquery validator验证框架验证表单

(4)分页bean的编写

(5)过滤器，拦截器的编写

(6)泛型dao的编写

二、实例

1、数据库脚本

本例是采用mysql数据库，脚本如下:

2、表现层

(1)login.jsp(登录页面)

(2)logout.jsp(退出页面)

(3)exception(错误异常显示页面)

(4)studentList.jsp(学生列表页面)

4、逻辑处理Action层

BaseAction.java

package com.anxin.struts.action;

6、过滤器和拦截器

LoginFilter.java(jsp页面过滤器)

package com.anxin.filter;
